1 The principal objects of the present inven- 4 tion are to provide asatisilactory and eflicient 5*the fire; to obviate objectionable accumula circulation of water; to insure an eflicient exposure of the heating surface of the unit to tions of dirt" and of; duston the outside of the unit; to provide against cloggingoi the Water ways; and toaiford an extended heati 'ing surface.

" Other objects of invention will appear from the followingdescription at the endof I whichthe'invention will be claimed but it may be said that,-'generally stated;- a water heating unit of the invention comprises a hollow annular bodyof flattened elliptical body and arranged betweenthe inlet and form in cross section and corrugated on the outside and having closely spaced water inlet and outlet connections andincluding a partition or baflle disposed in theiplane of the y 1 outlet connections to provide water ways and ported opposite said connectionsto afford communication betWeen'said-water Ways.

There is a hollow annular body of flats 'tened elliptical form in crosssection, Fig.3.

This provides a surface '2, generally inclined to the horizontal and from which dust by readilyfalling is not permitted to accumulate. I

" The body 1 ontheoutside or periphery is cor rugated to provide an extendedheating surface. The Water inlet'andoutlet' connections 3 and 4 are closely spaced. 5 is a partition or baflie plate disposed in the planeof the body and varran'gpd betweenthe inlet and outlet] connections 3 and 4 to provide unobstructed water ways 6 and 7, and this partition or 1 50 baffle plate is ported opposite the connections
